Network externalities (product's value to a consumer changes as the number of users of the product changes) are so incredibly strong that few monopoly powers and eventual market failure is inevitability.

If you could run multiple parallel universes starting from early 90's, you would end with just handful of companies dominating the markets and using one service or product to leverage to other areas in almost all of them. Just the names of the companies would change.
